IMPROVEMENT IN GRAIN-DRYERS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, HENRY BODEN, of Olney, Richland county, Stateof Illinois, have invented new and useful improvements in Grain and Flour-Dryers; and I do hereby declare thefoltowing to he an exact description thereof, reference being bad to the accompanying drawings, and to theletters of reference marked thereon, making a part of this specification, in which- Figure 1 represents a side elevation of the machine.

Figure 2, a vertical section.

Figure 3, the view of top chamber, showing the angle of the scrapers.

Figure 4, view of the second chambeflshowing the opposite angle of the scrapers.

The nature of my invention consists in the arrangement, construction, and combination of the steamchambers with their receiving and discharge pipes, draught fines, and coolers below.

A represents the square upright frame that supports the 'devices of the machine; B the vertical shaft or centre spindle to be operated at top by any proper gearing. G G O are the three steam-chambers located at top, one below the other. D D D are the three coolers underneath the chambers 0, one below the other.-

E E E E are the steam pipes that conduct the steam to the top chamber 0 through the second chamber C, and discharge the steam at the lower or third chamber 0, thus heating the chambers O by steam, and drying the rain without burning it. The flue G passes from the bottom to the top (as designated by the arrows) on each side of the coolers, to carry cool air across the coolers and assist in drying the grain or flour. 'The grain is first conducted by spouts to the top of the first chamber C, where the scrapers H, attached to the arms J extending from the spindle B, sweep the grain from the centre to the periphery of the chamber 0, until it falls down upon the second chamber 0 protected by a flange, L. Here the grain is swept by the scrapers H to the centre by the scrapers being at reverse angles from the top scrapers, and the grain falls through the aperture of the chamber surrounding the spindle B, the scrapers continually sweeping the grain to and through the centre aperture. As the grain falls upon the third chamber 0 the scrapers H sweep it from the centre, over the outer edge of the chamber C, on to the first flanged cooler D. The scrapers H now sweep the grain to and. through the centre aperture, and as it falls upon the second cooler D the scrapers H sweep the grain from the centre, and over the outer edge of the second cooler D on to the lower cooler D, that catches the grain by its flange L, and the scrapers H'sweep the grain to and through the centre aperture to the receptacle or floor M beneath. The grain, as it passes from the top chamber 0 to the first cooler D, is gradually heated, and as it passes from the first cooler D, to and through the third and last cooler D, is gradually cooled, and falls upon the floor M beneath, properly dried.

I do not claim heated chambers or hot-air chambers and coolers for drying grain, placed one above the other, but what I claim as my invention, and desire to secure by Letters Patent, is-- The arrangement and construction of the steam-chambers C C G with their receiving and discharge steam pipes E E on the outside, and draught Hues G on each side of the coolers D D D below, when arranged, constructed. combined, and operating as herein described and for the purposes set forth.
